摘要： A high strength cast metal racquet wherein string guides protrude into the striking area of the racquet frame but are offset from the plane of the strings. The string guides contain apertures perpendicular to the plane of the strings. The string guides permit the strings to be strung in a plane bisecting the frame of the racquet.
